Cook the tortellini according to package instructions. Drain and rinse with cold water.
Add tortellini to a large bowl. Add cooked corn, black beans, bell pepper, avocado, cherry tomatoes, onion, and cilantro.
Combine all of the dressing ingredients in a resealable jar. Shake until combined. Pour desired amount of dressing (you may not want to use it all) over the pasta and toss to coat.
Tortellini: Although the dry packaged kind will work for this recipe, I just don't think they taste as good. The refrigerated kind only take a few minutes to cook once your water is boiling and they're much better tasting.Variations:
Add protein: grilled chicken, tofu, shrimp or steak.
Substitute what you already have! Use your favorite kind of beans, and incorporate other veggies you like or already have on hand.
Adjust Spice: add some hot sauce to the dressing, to turn up the heat.
Dressing: if you don't want to make it from scratch (sigh!) you can add your favorite store-bought zesty southwest or Italian.
Make Ahead Instructions: Cook the tortellini, chop the veggies and make the dressing, but store separately. Combine everything just before serving!
